こんにちは。私はJavaとGWTの新機能です。 Filenetからいくつかの値を取得するためにRPCコールがあります。GWTを使用しています。ここでRPCコールを使用しています。着信RPCコールをディスパッチする際の例外
リモートサービスを拡張するFcInterface.javaには3つのメソッドがあります。インタフェースの2つのメソッドは、serberからclientに値を返すようにうまく機能しています。しかし、第3の方法では問題がありますが、サーバー側からクライアント側に値を返すことはできません。
コードをスタックトレースに付加する。クラスの
はCode:
public class FilenetCmisServiceImpl extends RemoteServiceServlet implements FcInterface {
...
...Some codes
public Map<String, Object> getContentOfRootFolder(String RepositoryId) {
Map<String, Object> ContentOfRootFolder = new HashMap<String, Object>();
ItemIterable<CmisObject> children = root.getChildren();
for (CmisObject o : children) {
FilenetFolderImpl folder= new FilenetFolderImpl();
folder.setFolderName(o.getName());
folder.setFolderId(o.getId());
folder.setFolderModifiedBy(o.getLastModifiedBy());
folder.setFolderClass(o.getBaseTypeId().toString());
folder.setFolderModifiedOn(o.getLastModificationDate());
System.
out.println("name : " + o.getName());
ContentOfRootFolder.put(o.getName(), folder);
}// every thing is fine till here
return ContentOfRootFolder;
}
}
コードFilenetFolderImpl
public class FilenetFolderImpl {
private String FolderName;
private String FolderSize;
private String FolderModifiedBy;
private GregorianCalendar FolderModifiedOn;
Folder root;
private String FolderId;
private String FolderClass;
public FilenetFolderImpl(String Foldername){
this.FolderName=Foldername;
}
public FilenetFolderImpl(String name, String id, String baseTypeId,
GregorianCalendar lastModificationDate, String lastModifiedBy) {
// TODO Auto-generated constructor stub
this.FolderName = name;
this.FolderId = id;
this.FolderClass = baseTypeId;
this.FolderModifiedBy = lastModifiedBy;
this.FolderModifiedOn = lastModificationDate;
}
public FilenetFolderImpl() {
// TODO Auto-generated constructor stub
}
public String getFolderName() {
return FolderName;
}
public void setFolderName(String FolderName) {
this.FolderName=FolderName;
}
public String getFolderId() {
return FolderId;
}
public void setFolderId(String FolderId) {
this.FolderId=FolderId;
}
public String getFolderClass() {
return FolderClass;
}
public void setFolderClass(String FolderClass){
this.FolderClass=FolderClass;
}
public String getFolderModifiedBy() {
return FolderModifiedBy;
}
public void setFolderModifiedBy(String FolderModifiedBy) {
this.FolderModifiedBy=FolderModifiedBy;
}
public GregorianCalendar getFolderModifiedOn() {
return FolderModifiedOn;
}
public void setFolderModifiedOn(GregorianCalendar gregorianCalendar) {
this.FolderModifiedOn=gregorianCalendar;
}
protected Map<String, String> addFolder(){
Map<String, String> newFolderProperties = new HashMap<String, String>();
newFolderProperties.put(PropertyIds.OBJECT_TYPE_ID,"cmis:folder");
newFolderProperties.put(PropertyIds.NAME,FolderName);
return newFolderProperties;
}
}
のStackTrace私は推測

がシリアライズに問題があるか、私は型であるContentOfRootFolderを使用してFilenetFolderImplのobectを送るカント Map<String, Object> ContentOfRootFolder = new HashMap<String, Object>(); いずれにしても、私はFilenetFolderImplの値を返す必要があります。
この問題を解決するのを手伝ってください。おかげさまで
